To all whom 'it may concern:

Be it known that I, WILLIAM BoorH, a

citizen of ythe United States, residing 1n Gladwyne, Montgomery county, Pennsylvania, have invented certain Improvements in Lubricators, of which the following is a specification.

My invention relates to devices for applying oil or other lubricant to wool or other textile fibers as they are being fed to a machine, such, for instance, as a carding machine or a Garnett machine whereby the bers are acted u on after the lubrication of the same, the object of my invention being to insure the uniform lubrication of themass offibers by preventing either the overloading of the same with oil or the application of an insuficient amount of oil thereto. This object I attain by regulating the supply of oil which is being fed to the mass of fibers, so that the volume of the su ply will 'accord with the volume of t e mass to be lubricated.

In the accompanying drawings Figure 1 is a view, partly in elevation and partly in transverse section, of apparatus constructed in accordance with my invention, and Fig. 2 is a view 0f the same, partly in elevation [and partly in longitudmal section.

In the drawing, 1 represents a feed belt or apron for conveying the wool or other fiber (hereinafter, for convenience, termed wool') to the machine which is to act upon the same, 2 a suitably rotated brush located above the feed belt and extending aross the same from side to side, and 3 a 'fixed blade or plate engaging with the pro- The pipe which delivers oil to the brush' usually consists of a fixed under member 4 and a lower member 4F' pivotally connected thereto, this lower member being intended to be vibrated by suitable connections, so that it will deliver the oil from endto end of the 2, AS an instance of y conveyer 1.

available for the purpose reference can be had to the patent of Gr.` A. Spencer, No. 553,628, dated Januar 28, 1896. The objection to lubricating evices of this typte as heretofore constructed has been that they provide a substantially uniform supply of' oil, the only means of regulating the volume of flow being the hand operated valve 19 in the for regulation of the volume of flow atithe beginning of the operation to accord with the general thickness of the mass of wool, it is not possible, with it alone, to Veffect constant variations in the volume of oil supply necessar to accord with local variations in the thic ess of the mass, which, in practice, frequently occur, consequently the thinner portlons of the mass receive a surplus of oil while the thicker portions ofthe mass are inspuiiciently lubricated. The v,object of my invention is to overcome this defeet in previous lubriCatOrS, and this object I attain by the use of what may be termed a detector roll, which rests upon thel mass of wool on the conveyer belt or apron and rises and falls in accordance with the variations in the thickness of said mass, these movements of the detector roll being caused to operate a valve in the oil supply pipe and thereby accurately regulate' the flow of oil to accord with the requirements of the case, and thus effect uniform lubrication.

In the drawing, 5 represents the-detector roll, which may extend completely across the apron, or may be of lesser length, as desired, this roll being mounted so as to be free to turn on or with a spindle at the .lower end of a rod 6, the upper end of which Patented Nov. l14, 1911.

pipe 4. While this is available' is connected to one arm of a lever 7 suitably mounted above the feed belt or conveyer 1, the other arm of said lever carrying a counterbalance weight 9, which is adjustable pn said arm of the lever so as to counterbalance the weight of the ldetector roll and its supportin rod whatever such weight may be. T e lever 7 is, also connected to the stem 10 of a valve 11'which is free to slide vertically in a valve chest 12, the latter being iixedl mounted and inserted in the fixed mem er 4 of the oil slpply pipe which connnumcates with an oil reservoir 13 likewise ixedly-.mounted in any convenient position above the feed belt or In' the' present instance the valve chest `12 is provided ywith front and rear branches 14 and 15, which are secured by detachable couplings 16 t0 adjoining sections of the fixed member of the oil supply pipe, but it will be' evident that otherl means of)mounting the .valve chest and providing for its communication with the oil supply ipe mayf be adopted withoutdeparting om my invention. v The valve 11 consists, in the present instance, of'a tube open at both ends and having oppositely'r` disposed ports 17, which,

when they register with the/bores of the branches 14 'and `15, permit a VJfull and .free supply 'of oil to pass from the tank 13 to and through the pipe 4, 4*, this being the v position of the valve when a mass of wool of ,A the reduced volume of wool to be lubricated,-

thus again opening the valve to a corre-l sponding degree and l{Lwrermitting' a flow of oil of pilplper volume At ough the pipe 4, 4". By ma g the valve 11 tubular and open at both ends the oil can flow freely through the valve from the' chamber below the same to v brush by the timethe increased or` reduced chest below the valve.

While I prefer in allcases to use a detector o roll for running upon the top of the mass of wool.dep osited upon the conveyerpbelt or apron, this roll'may, 1f desired, be supplanted by a plateor shoe for bearing upon thev y.top ofusaidmass, the roll, however, having le'ss .tendency to,vv disturb or displace the fibersgthan would.. a lfixed'fbearing` device.
